  • DETAILED DESCRIPTION
  • The present invention relates generally to a connector system and more particularly to a connector system which includes a universal serial bus interface. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiments and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features described herein.
  • FIG. 1 illustrates a conventional female USB connector 10. The connector 10 includes a housing 14. The housing 14 is typically enclosed within a device such as a computer, PDA, printer, digital camera or other device. The connector 10 as is seen has four pins 16, 18, 20 and 22, for allowing for connections to a male connector.

  • FIG. 4 illustrates the conventional USB connectors 10 and 30 after they have mated. It is desirable to provide additional functionality into this type of connector, particularly with a connector that has a standard interface such as a USB interface, while not increasing the overall size of the connector or creating more complexity in the connector or requiring an additional connector.
  • Accordingly, the present invention provides for a system for addressing the above-identified issues by providing additional signal pins within both the male and female connectors such that they can add additional functionality. The additional functionality could be, for example, video, audio, or other types of functionality to the particular system. For example, it may be desirable in a device such as the Apple iPod to provide such a connector to provide audio or video input/output lines directly to a device to which it is connected, even if no such dedicated IO lines are otherwise available. Accordingly, in the present invention, a male and female connectors are provided that include additional pins within the connector that provide for additional functionality. This is accomplished utilizing the standard interface of the USB connector but adding additional pins around that interface to provide this functionality. To describe the features of the invention in more detail, refer now to the following description in conjunction with the accompanying figures. FIG. 5 is a front view and FIG. 5A is a perspective view of the female connector 100 in accordance with the present invention. As is seen, it includes the same four pins 16′-22′ as the conventional female USB connector 10 of FIG. 1 on plate 103 within housing 105. It also includes five additional pins 102, 104, 106, 108 and 110 which can be used for additional functionality. The additional pins are placed in between the plurality of USB pins such that the USB pins can engage a conventional USB connector. In this particular embodiment, the additional functionality is for a serial data in pin, a serial data out pin, audio right, audio left and audio ground. As is seen, the four pins 16′-22′ satisfy the USB interface standard while five additional pins 102-110 are provided therewithin to add for the additional functionality. As before mentioned, this female connector 100 can then be mated with a male connector that has the complimentary pinout. As illustrated in FIG. 5A, the pins can be spring-loaded to engage the circuit traces of a male connector, but they may be of any conventional construction that accomplishes the mating between the complimentary pins on the male and female connectors. FIG. 5B is a drawing of illustrating detailed dimensions of a female connection in accordance with the present invention.
  • Table 1 below illustrates the specific pin out for the female connection 100. As is seen, USB pin 1 (pin 16′) is a power pin, USB pin 2 (pin 18′) is a data−pin, USB pin 3 (pin 20′) is a data+pin, and USB pin 4 (pin 22′) is a ground pin. As is further seen, additional pin 5 (pin 102) is a serial data to device pin, additional pin 6 (pin 104) is a serial data from device pin, additional pin 7 (pin 106) is an audio common pin, additional pin 8 (108) is an audio left pin and additional pin 9 (pin 110) is an audio right pin.

  • FIG. 6 illustrates a front view of a male connector 200 in accordance with the present invention. The male connector 200 as seen has the identical four circuit traces, 32′, 34′, 36′ and 38′ as shown in the conventional USB male connector 30 of FIG. 2, but it also includes the additional functionality of five additional circuit traces, 202, 204, 206, 208 and 210 on circuit board 203 within housing 205. In so doing, a female connector 100 of FIG. 5 can be mated with the male connector 200 to provide the additional functionality. FIG. 6A is a drawing illustrating detailed dimensions of a male connector in accordance with the present invention.
  • A key feature of the present invention is that both of these connectors can be utilized with the conventional USB connectors. To illustrate this feature, refer now to the following description in conjunction with the accompanying figures.
  • Referring now to FIG. 7, what is shown is the male connector 200 of FIG. 6 mating with the female connector 100 of FIG. 5. In this embodiment, as is seen, the four pins from the male connector 200 can engage the appropriate four USB connector pins of the female connector 100, and the USB connection will operate in an effective manner. FIG. 8 illustrates the connectors 100 and 200 of FIGS. 6 and 7 after mating.
  • FIG. 9 illustrates the conventional USB female connector 10 of FIG. 1 and the male connector 200 of FIG. 6 before mating. FIG. 10 illustrates the female connector 10 of FIG. 1 and the male connector 200 of FIG. 6 after mating. These figures illustrate that the male connector 200 in accordance with the present invention can also be engaged with the conventional female connector 10.
  • FIG. 11 illustrates the conventional USB male connector 30 of FIG. 2 and the female connector 100 of FIG. 5 before mating. FIG. 12 illustrates the male connector 30 of FIG. 2 and the female connector 100 of FIG. 5 after mating. Similarly, these figures illustrate that the female connector 100 in accordance with the present invention can also be engaged with the conventional male connector 30.
  • Accordingly, what is provided is a connector which has additional functionality which incorporates conventional standard functionality of a USB connector while also including the additional functionality which incorporates the additional pins within that connector. In so doing, a system is provided which is more versatile and can be utilized in a more robust way than previous connector systems. In addition, either connector can be used with a standard interface. It is compatible with existing systems. One should readily recognize that although the present invention has been described in conjunction with the USB interface, this system could be used within a variety of environments and they would be within the spirit and scope of the present invention. Although the standard USB interface is utilized as example, one of ordinary skill in the art readily recognizes that a variety of other interface standards which may be present now or which may come in the future could be utilized in such a system, including for example, USB 2.0, mini USB, IEEE 1394, etc.
  • It will be clear that the invention described herein provides significant functional enhancements when incorporated into prior art systems. FIG. 13 shows an exemplary system 300 using the connector described herein. The system includes at least two devices 302 and 304 to be connected together. Each device 302 and 304 contains an enhanced USB connector interface 402 a and 402 b as described herein. They can be connected together via cable 404 (which is modified to contain extra wires to match extra pins in the enhanced connector). Alternatively, one of the devices can be itself constructed integrally with the USB connector so that it can be docked in place when mated with the other device, for example, as is done with flash-backed memory sticks, or similar devices that include an integral USB connector. When connected together, the devices can exchange data via the enhanced connector signals that would not be conveniently possible but for the existence of the additional functional signals.
  • For example, one device (a media player) can provide video or n-channel audio data to another device (a television or speaker set) without requiring extra cables. This could be especially useful in devices that are too small or inexpensive to have dedicated IO lines for video or audio data. Again using the example of a device with integral USB interface, such a device could be configured as a media player to be mated with a speaker housing that receives both the audio output data and any additional menu or control data via the same enhanced USB interface.
  • Although the present invention has been described in accordance with the embodiments shown, one of ordinary skill in the art will readily recognize that there could be variations to the embodiments and those variations would be within the spirit and scope of the present invention. Accordingly, many modifications may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims.
